  • To adjust the position of the Control cam can be a hexagonal actuator rod with a hexagonal cross section one end and a gear on the other end. If the hexagonal control rod is rotated, the gear rotates a shaft on which one adjustable component is attached. Due to an internal thread of the Control curve and the fact that the control curve cannot rotate rotating the shaft will shift the cam.
  • a compression spring acts Movement of the control curve opposite, so that the various components of the Adjustment mechanism can not move without sufficient torque of the hexagonal control rod.
  • the hexagonal control rod for the Setting an adjustable component can be used in a printing press.
  • the compression spring on the control cam is known to work not trouble-free or is worn out after a while and does not deliver enough Resistance, although it still allows adjustment of the hexagonal control rod.
  • the present invention provides a position controller comprising an actuating rod, which has a first end with at least three flat sides, a second end, one with the adjustable component connected by the rotation of the second end Adjustment rod can be adjusted, and a first and a second set of Has leaf springs, the first set of leaf springs having a first and the second Set of leaf springs with a second of the at least three flat sides of the actuating rod interact.
  • the leaf springs create an opposing torque for the various components of the position controller.
  • the first end of the actuating rod has six flat sides, i. H. it is hexagonal shaped.
  • the first set of leaf springs acts on the first of the hexagonal sides and the second set of leaf springs preferably acts on the second of the hexagonal sides, with the second side directly opposite the first side.
  • the first set of leaf springs is parallel to the second set located.
  • Each set of leaf springs can be a single or preferably a plurality of leaf springs include.
  • the counter torque generated by the leaf springs on the adjusting rod can effortlessly by changing the properties, number and / or thickness of the leaf springs can be varied, but a back torque of 10 to 15 inches x lb (about 1,130 to 1,695 N x m) is for one normal ink roller storage in a printing machine is a preferred value.
  • the present invention advantageously generates for the revolutions of the Control rod, both clockwise and counter-clockwise, the same Counter torque.
  • the holding force or counterforce generated by the leaf spring sets acts across a large surface area, causing surface wear minimized. No special settings are required. Friction, as with a thread ratio arises, is not used here to generate resistance used, so that the separation of threads is not a problem.
  • the present Invention allows a compact construction and also allows the control rod moves axially or "floats" in a third direction while still a Offers torque resistance in the other two directions.
  • a cover can be provided over the leaf springs to prevent contamination prevent or minimize.
  • the cover can either cover the first end, or the first end may protrude from an opening in the cover.
  • the present invention is used advantageously for setting rollers in a printing machine and especially for adjusting the position of an inking roller applied.
  • the adjustable component is preferably a control curve for the Setting an inking roller.
  • the position controller 10 comprises a hexagonal adjusting rod 12 with a hexagonal cross section at one end 14 and a gear 16 at the other End 18.
  • the actuator rod 12 is used for adjusting the position of an adjustable Component 20 used in the printing press 1.
  • the adjustable component 20 can e.g. B. be a control curve for adjusting the position of an inking roller.
  • the adjustable component 20 having an internal thread is also on one attached with a threaded shaft 22 and thus by the thread with this connected.
  • the shaft 22 is supported by arms 21 and is one end of the shaft formed as a (second) gear 26, which with the gear 16 of the hexagonal actuating rod 12th interacts.
  • One side of the adjustable component 20 interacts with a housing section 30 of the printing press to rotate the adjustable To prevent component 20, but a displacement along the shaft 22 permit.
  • the housing section 30 also supports the one held by the arms 21 Shaft 22 in a rotatable manner.
  • a Compression spring 24 provides resistance to the movement of component 20 so that the various components of the adjusting mechanism without sufficient torque the hexagonal control rod 12 can not move.
  • FIG. 2 shows a position controller 40 according to an embodiment of the present Invention with a hexagonal adjusting rod 42, a first leaf spring set 46 and a second leaf spring set 48.

  • the second leaf spring set 48 is in Interaction with the second flat side 45 (however, these sides change with the rotation of the control rod 42).
  • Each leaf spring set 46, 48 has a plurality of leaf springs, each leaf spring has a certain thickness and a flat, thin, preferably rectangular Metal plate is made up of a certain spring resistance or spring constant having. Each flat, thin plate has a hole at one end provided (not shown) into which a fastener is fitted around the leaf spring to keep in place.
  • the first leaf spring set 46 is a fastening element 47, z. B. assigned a screw or nut-screw combination and the second Leaf spring set 48 is also associated with a fastener 49.
  • the fasteners 47, 49 can connect the sets of leaf springs to a housing 3.
  • the sets of leaf springs 46, 48 are more advantageous Arranged parallel to each other, although they relate to each opposite sides of the hexagonal adjusting rod 42 are located. It goes without saying itself that the leaf springs interact with the hexagonal adjusting rod 42 in order to to create a resistance to the rotation of the actuating rod 42. Thus prevented position controller 40 of the present invention undesirably rotates the Actuator rod 42 or other connected components.
  • position controller 40 and those shown in FIGS. 3 and 4 can Position controller together with the device of the prior art shown in Fig. 1 Technology are used, or advantageously with a device in the spring 24 shown in Fig. 1 is eliminated.
  • FIG. 3 shows a position controller 50 according to a further embodiment of the present invention in which a first set of leaf springs is a single leaf spring 56 and a spring piston 57 which the leaf spring 56 against a flat surface of the hexagonal actuator rod 52 forces.
